Infineon diodes enable AC/DC power-conversion apps
Infineon Technologies
SiC Schottky
Infineon's 2nd generation SiC Schottky diodes enable active Power Factor Correction (PFC) in Switched Mode Power Supplies (SMPS) and other AC/DC and DC/DC power-conversion applications.
The TO220 Fullpak range is said to combine the high electrical performance standards of the 2nd generation Thinq SiC (silicon carbide) Schottky diodes with the advantages of a fully isolated package, including easier and more reliable mounting without having to use isolating bushing and foil.
The TO220 Fullpak devices show a similar junction-to-heatsink thermal resistance as the standard non-isolated TO-220 devices.
This is accomplished using a diffusion-soldering technique from Infineon, which reduces the chip-to-leadframe thermal resistance and effectively compensates for the Fullpak's internal isolation layer.
Infineon offers the 600V Fullpak portfolio in current ratings from 2 to 6A.
Key features are a benchmark switching behaviour, no reverse recovery, virtually no temperature influence on the switching behaviour and a standard operating temperature of -55 to 175C.
Products in the TO220 Fullpak portfolio are suited for power-supply application in flat-panel displays (LCD/PDP) and computers.
The SiC Schottky diodes are offered in 600V and 1200V.
